I'm new to the RCS South Loop (CV, ELC, NATCTY, LMGRV, LAMESA, CHP, SDSO, SDPD, etc). I'm working with a BC250D-P25 and trying to dial in most useful TGID lists. I've been using the RR database and running in search mode and reviewing logs (PROSCAN 4.3) to find the most relevant/used TGID in the area. However, the RR database lists numerous TGID that seem inactive (e.g. CHP outside ELC) and does not have others that are very active (I can't find a reference to 38883 which is very active.) Does anyone have any intel on exactly what 38883 is and/or have some useful guidance on dialing in these areas? For example, is there a local Community Of Interest, forums, blogs, etc? Any and all help is greatly appreciated.

Thanks for such a fast response. My owners manual is pretty skimpy on detail when it comes to status bits, but this clears everything up. Sorry this turned out to be a newbie question, and the help is much appreciated.

You can validate talkgroups by dividing them by 16. If it divides evenly, that is a valid talkgroup ID. If it is not even, you have found a patch group. Every base talkgroup WILL divide even by 16. Motorola radios are programmed with HEX numbers and are HEX based. Hex is a 16 base counting system.
